Answer:
Step-by-step explanation:
3x + x + 60 = 180.
first, we add the x's together.
4x + 60 = 180
then we see if they all have a common multiple. in this case, they do. they are all divisible by 4, so we can use that.
x + 15 = 45
then, just subtract 15 from both sides, that way we get the variable by itself.
x = 30
also, it is a right triangle. the top angle (3x) multiplied by 3 is 90. any triangle that has a 90 degree angle is automatically a right triangle.
Step-by-step explanation:
x² + 3 / x - 1 = x + 1
- x² - x
------------
0 x + 3
- x - 1
-------------
0 4
the remainder is 4
You have to get from $30 to $21.75
21.75/30=0.725 x 100= 72.5% of the original price
I think there is more to the question, but the equation to solve for the number of months until Rita has enough money to put a down payment for a condominium is 15,000=8,000+850X
